I’ve recovered 2TB of data from a faulty RAID5 NAS from a friend using System rescue CD. This included all of his personal pictures from the last 10 years.

I’m sure he wants to thank me, but it should be you/your team receiving the credits. To my surprise there is no donate button on your website. I found a link in the forum pointing to http://www.fsarchiver.org/donate, but that is no longer valid.
